JESSE OHMERT, OF MOUNT MORRIS, ILLINOIS.

OVEN.

To all whom t may concern.'

Be it known that I, JESSE OHMERT, of Mount Morris, in the county of Ogle and State of Illinois, have invented a new and useful Improvement in Bakers Ovens; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a longitudinal sectionof my improvement, (x), Fig. 2 showing the plane of section. Fig. 2, is a transverse vertical section of the same, (y), (y), Fig. 1, showing the plane of section. Fig. 3, is a horizontal section of the same, (e), (z), Fig. 1, showing the plane of section. Fig. 4, is also a horizontal section of the same, (a), (e), Fig. 1, showing the plane of section.

Similar letters of reference indicate corresponding parts in the several figures.

lIy invention consists in a peculiar arrangement of the flues of the oven as will be hereinafter fully shown and described, whereby the heat from the furnace is made to pass entirely around the oven, and the oven exposed to a large volume of heated air and of the proper temperature.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the furnace which is of rectangular form and constructed of cast iron. This furnace is divided into two compartments by a horizontal partition B. In the lower compartment is the fire chamber C, having a longitudinal passage or flue (a), at each side. These iues communicate with the fire chamber C, by means of openings made through the back end of the fire chamber and at each side of a vertical partition (c), see Figs. 1, 2, and 3, which divides the two flues The upper compartment of the furnace A, has a rectangular chamber D, within it, as shown clearly in Fig. 4. The chamber D, is considerably smaller than the furnace so as to allow a space to extend around it, said space being divided into two parts by vertical partitions (cZ), (CZ), so as to form two fines (e), (e), shown clearly in Fig. 4. The chamber D, has an aperture (f), made in one of its sides as shown in Figs. 1 and 4; and the horizontal partition B, within the furnace A, has two apertures (g), (g), made through it at its front end, an aperture being in each flue (e), and also two apertures (71,), (it), through its back end, one in each flue (e), the apertures (L) have dampers (i), over them. The apertures (g) it), form a communication between the fluees (a), (a), (e), (e), as shown in Figs. 1 and 2.

I), represents a semi-cylindrical casing which may be constructed of sheet or cast iron. This casing has a bottom which fits' directly over the compartment of the furnace A, and apertures (7c), (7c), are made through its back end, an aperture communicating with each flue (e), in the upper compartment of the furnace, see Fig. 1 and dotted lines in Fig. 2. Within the casing D, the oven E, is placed. The oven is somewhat smaller than the casing so as to allow a space (Z), between its back end sides and top and the casing see Figs. 1 and 2.

F, is the smoke pipe on the upper part of the casing at its front end.

From the above description it will be seen that when the dampers (z'), are closed the heat, smoke, etc., from the lower compartment or lire chamber of the furnace A, will pass through the apertures (b), (b), at the back end of the fire chamber and toward the front end of the furnace through the flues (a), (a), thence upward through the apertures (g), (g), into the flues (e), (e), of the upper compartment of the furnace the heat passing through the aperture (f), into the chamber D and heating the bottom of the oven and then passing upward through the apertures (7c), (lo), into the space (Z), around the oven, the smoke escaping into the pipe F, see arows. Thus it will be seen that the heat is made to pass entirely around the oven with the exception of its front end, and the heat is properly tempered by means of the chamber D, and the flues (e), (c), in the upper compartment of the furnace, that is the oven is not in contact with the fire chamber and consequently one part of it will not be subjected to a much greater heat than another part; and owing to the circuitous passage of the flues no heat is lost or allowed to pass into the smoke pipe F, as it would be absorbed before or at the time of reaching said pipe.

When a direct draft is desired for kindling the fire, etc., the dampers (i), are

opened and the smoke and heat Will pass chamber C, and oven E, as herein described directlyY into the space for the purpose specified.

Having thus described my invention what w I claim as new, and desire t0 secure bi1 Let- JESSE OHMLRT' 5 ters Patent is, Witnesses:
